Can a seismic design be transposed between countries?

No. Philosophies converge, but parameters are local: hazard map, soil classes, national annexes. Every site requires its own calculation by a licensed engineering office.

Building in seismic zones: principles and codes

An earthquake-resistant building is not a heavier building: it dissipates energy without collapsing. In Indonesia, design is governed by SNI 1726:2019; in Europe, by Eurocode 8. The same principles everywhere: site soil governs the design spectrum, geometric regularity protects, ductility saves.

What does a seismic code require, in one sentence?

That the building protect lives for its site's reference earthquake: the soil is classified, a design spectrum follows, geometry is disciplined (soft storeys and eccentric masses are prohibited or penalised), and reinforcement detailing gives the structure the capacity to deform without breaking.

Where are the applicable requirements written?

In Indonesia: SNI 1726:2019 (Badan Standardisasi Nasional), built on the 2017 hazard map, with the Ministry of Public Works' official spectrum tool. In Europe: Eurocode 8, declined through national annexes. This guide's articles unfold these requirements in investor language.

What the house verifies before committing

A dated, signed geotechnical study; drawings citing the applicable code; independent site inspection; logged tests. Documentary discipline is the best predictor of a structure's real seismic quality.
